d&b audiotechnik has introduced its B4-SUB subwoofer. The enclosure houses two, long-excursion, neodymium drivers: a 15-inch driver in bass-reflex design facing to the front; and a 12-inch driver in a 2-chamber band-pass design radiating to the rear. According to the company, the design reduces unwanted level behind the cabinet by more than 15 dB over its entire operating bandwidth and provides accuracy in low-frequency reproduction extending from 40 Hz to 150/100 Hz. Each channel of a d&b D6 or D12 amplifier drives up to two loudspeakers with the B4-SUB configuration selected.

The B4-SUB is specifically designed for ground-stack use only; an M20 threaded flange in the top panel accepts a loudspeaker stand, while two runners extend from front to rear of the bottom panel and fit to correspondingly shaped recesses in the top.
